I have the same issue. I've run the 2016.2 Version Utility upgrade (on a .NET ASP.NET website) on my WIndows 10 PC (which was upgraded from WIndows 7).

The log file show the following error :

02:19:35: Running User Interface Version 16.2.20162.1000
02:19:35: Gathering volume and assembly information.
02:19:35: Could not locate registry entry Software\Microsoft\.NETCore\v4.5\AssemblyFoldersEx where we look for installed products.

I have got NET frame work install (4.5) - but there is no registry entry for v4.5 on my PC (just previous versions). I need to upgrade an ASP.NET project from 11.1 to 16.2

I installed version 2015.2, and am seeing a new error when trying run the version utility. Here is the log file:

Does this give any additional information to go on?

I haven't been able to isolate the cause of this.  When upgrading smaller sites, the tool works as expected. When run on our large legacy web site (note that it's a Visual Studio website project, not a web application), it fails: no errors displayed in the text error, only the attached error printed in the log file.

I'll see if I can replicated it with a demo site, but I have continued on with the upgrade without the tool.

Thanks,

Seth
